"Revolution" is an epic, swashbuckling drama from J.J. Abrams' Bad Robot Productions and "Supernatural's" Eric Kripke. With sweeping scope and intimate focus, this show centers on the Matheson family's struggle to survive 15 years after a mysterious worldwide blackout. Their post-apocalyptic world is juxtaposed with bucolic, overgrown cities and a journey of hope, rebirth and retribution.

For the traditional 2012-13 TV season, "Revolution" averaged a 4.3 rating in adults 18-49, tying it as the #8 primetime series on ABC, CBS, NBC and Fox (excluding sports pre- and post-game shows) and making it the #1 10 p.m. drama on those networks. "Revolution" was the second-youngest drama on ABC, CBS or NBC, with a 46.7 median age for its audience (placing behind only "Hannibal's" 45.3).

Season two picks up six months after the season one finale with ICBMs speeding toward Atlanta and Philadelphia. Last season, Rachel's (Elizabeth Mitchell, "Lost") relentless quest to avenge her son's death sent her on a heroic journey to the Tower, where she could turn the power back on so the Rebels and the Georgians could wage war against Gen. Sebastian Monroe (David Lyons, "ER") and defeat his treacherous Militia. Aaron Pittman (Zak Orth, "Romeo + Juliet"), a major player at Google, joined her on this suicide mission with the hope of restoring the world's technology. Miles (Billy Burke, "The Twilight Saga") discovered that Monroe was waiting at the Tower for Rachel and mounted a rescue mission with Charlie (Tracy Spiridakos, "Being Human"), Tom Neville (Giancarlo Esposito, "Breaking Bad"), Jason Neville (J.D. Pardo, "The Cinderella Story") and Nora (Daniella Alonso, "My Generation").

But our heroes soon discovered that former Dept. of Defense Secretary Randall Flynn (Colm Feore, "The Borgias") had outwitted Monroe and hijacked the Tower for a sinister "Patriot" scheme. With help from a very reluctant Aaron, Randall turned the power back on and used the surge to deploy nuclear bombs at the Eastern seaboard.

For four minutes, the power came on across the globe creating what is now known as the Surge. But something mysterious happened to our heroes during this surge…
